Application filed October 23, 191.3. Serial No. 796,906.

T o all whom it may concern -Be it known that I, `WILLIAM M. FRiTsoHE, acitizen of the United States, residing at Mangum, in the county of Greerand State lof Oklahoma, have invented certain new and usefulImprovements in Detachable Heels; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to detachable rub ber heels, and one of theprincipal objects thereof, is to provide means for securely holding aheel' in detachable position on a shoe, at the same time allowing ofeasy detachment of the heel, without danger however of the heel becomingaccidentally removed while in use.

Another object of the invention is the provision of a detachable heelwhich will be simple, durable, efficient in operation, and inexpensiveto manufacture.

With these and other objects in view the invention consists intheconstruction, combination, and arrangement of parts hereinafter morefully described and claimed and illustrated in the accompanyingdrawings, in which like reference characters indicate like partsthroughout the several views, and in which,

Figure 1, represents a vertical longitudinal sectional view through theheel of a shoe, showing the attachable heel in place thereon. Fig. 2,represents a bottom plan view of a heel of a shoe, showing one of theattaching plates secured thereon, the removable heel being removed. Fig,3, represents a plan viewv of the removable' heel showing the otherattaching plate in position thereon. Fig. 4:, represents a plan view ofthe detachable heel showing a modification of one of the attachingplates secured thereon, and F ig. 5, represents a transverse sectionalview of a shoe witha modified form of detachable heel secured thereon.

Referring more particularly to the drawing, numeral 5, indicates theleather shoe heel and .6,l indicates a detachable heel, which ispreferably formed of rubber, but which may be formed ot' other materialwithout departing Vfrom the spirit -of the invention. i i

A shoe plate 7, which is substantially of the same shape as the shoeheel 5, but which and over which the is less in area than said shoeheel, is secured to the shoe by means of Vnails 8, and is provided withVspaced lugs or teeth 9;., slightly bent toward the shoe heel, and whichare adapted to bite into the leather of the heel when the plate isnailed in place. Secured 1n spaced relation around the edges of plate 7,are a plurality of ball members 10, of ball and socket clasps.

A heel plate 11, provided with downwardly extending edges 12, is moldedinto the rubber heel 6, the edges 12, being cut out or recessed atintervals as'at 13, whereby teeth or prongs 14;, are formed, betweenrubber is molded, whereby the heel plate is secured in place on theheel. That portion of the heel G, inclosed within the downturned edges12, is cut away to form a recess 15, into which the ball members 10,project, when the heel is secured in place, said heel plate 11, being-provided with a plurality of eyes 16,

through which the balls 10, are adapted to be forced in securing theheel in place.

The shoe plate 7, illustrated in Fig. 5, is provided with spaced roundbuttons 10, which are formed on the outer ends of Shanks 17, secured toplate 7', a button being situated near the ropposite edges of the plateat the forward portion thereof, and said plate is provided at its rearend with a turn button 18, secured by means of a shank 19, to the plate,said plate being formed similarly to plate 7. The heel plate 11, isformed similarly to plate 11, except that it is provided `with key holeslots 20, extending in the same direction, and in spaced relation, andis also provided with a rectangular slot 21, in which when securing therubber heel to the shoe, the turn button 18, is adapted to be inserted,said heel being'then turned until buttons 10, drop through the enlargedportions 22, of the lkey hole slots, said plate where the slots occurbeing stamped or bent downwardly as at 23, so that when the buttons 10,are inserted through the enlarged portions 22 of the 'key hole slots,the Shanks 17, will ride down the sloping portion of the heel plateuntil they reach the ends of the smaller portions 24, of the key holeslots, the plate at this portionbeing slightly converted in whichconcavities the buttons 10', are adapted to rest as illustrated in Figc.When the heel is thusb secured in place, the turn button 18,

along the key hole slots and it will thus be impossible to accidentallydisengage the rubber heel fromj the shoe. 'i In both the` modifications,the heel plate is molded into the heel and said heel is recessed orcutaway within the downturned edges of the heel plate., into whichv recessthe clamping means of the shoe plate extend. In detachlng the heel shownin Fig. 5, all that it is necessary to do is to turn the same until theenlarged portions 22, of the key hole slotsv register with buttons 10',whereupon the fore part of the heel may be forced slightly away from theshoe, thus disengaging the buttons through the enlarged portions of theslots, and by continuing the turn, the turn button 18, may be broughtinto registration with slot 21, whereupon the heel may be drawn awayfrom the shoe.

In removing the heel illustrated in Fig. 1, a knife blade or other Hatinstrument must be inserted between the heel and shoe and between theouter edges of plates 7 and 11, whereby the plates may be pried apart,thus separating the heel, any ordinary pull or forcing without the useof an instrument not being available to remove the heel from the shoe,and consequently there will be no danger of the heel becomingaccidentally loosened or removed from the shoe.

It is evident that by this construction when a heel gets `worn away, anew heel may be attached in its place, and without the reqirement ofskilled labor, and in a very short time, and in this connection shouldthe heels of a pair of shoes be run over or worn down on one side morethan on the other, the heels may be interchanged from one shoe to theother for obvious reasons.

Although I have described the preferred embodiment of my invention, Imay desire to make such' changes in the construction, combination andarrangement of parts as do not depart from the spirit ofsthe inventionand the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desireto secure by Letters-Patent is: l

1. Means for securing a detachable lift to a shoe heel comprising a heelplate arranged to be secured toa heel, a plate arranged to be embeddedin the detachable lift, shanks secured upon said heel `plate, and ballheads formed upon the ends of said shanks, said lift plate having key.holel slots formed therein, and its portions at thelsides of said slotsdeflected laterally and inclined longif tudinally, said lift plate alsohaving a lconcavity formed at the lower ends `otqeach of said slots andprojecting in oppositedirection to the side edges of said slots, wherebyto provide for the downward travel of said shanks through said slots andthe subse'- quent seating of said ball heads in said concavities forsecuring said lift to said shoe heel. Y 2. In combination with a shoehaving a heel, a plate secured to said shoe heel, a detachable heelmember for said shoe heel, a` plate embedded in said detachable heelmember, shanks secured upon said shoe heel plate, and ball heads formedupon the ends 'lasA of said shanks, said detachable heel member platehaving key hole slots formed therein, and its portions at the sides ofsaid slots deflected laterally and inclined longitudinally, said platealso having a concavity formed at the lower ends of each of said slotsand projecting in opposite direction to the side edges ot' said slots,whereby vto provide for the downward travel of said shanks through saidslots and the subsequent seating of said ball heads in aid concavitiesfor securing said detachable heel member to said shoe heel.'

In testimony whereof I have signed my name to this speciication in thepresence of two subscribing witnesses.
